Metal Production

Grip point is at the middle of the length, across the width of the bra. Pattern width extends over the grip point 5″ on the current product, 10.5″ on the future product. At grip point pattern, clearance is reduced to2 “. Bras (supported plates) must be picked up off a table with a 1” stand-off clearance. Wax pattern out of mold machine is unstable and requires gentle placement on cart.
Different diameter and height of plaster molds. Molds are manually handled, rotated, and transferred. End user would like to easily handle the molds in a safe manner that protects both the operator and product handled.
Molds to be handled are irregularly shaped with different sized multiple “legs” extending out and down from the mold pour cup. Gripping at the center of gravity of each mold is not possible, so manual rotation difficult. Molds are solid but brittle. Large work area to be covered by a manipulator.
Ingots are 24″ long. The zinc ingot is 9″ wide and the copper ingot is 3″ wide. They are gripped in random order and heated to 700°F. The furnace hood is 92″ from the floor. The top of the furnace is 48″ from the floor. The ingot must be placed into a pot that is 32″ and under the hood. Extended reach-in is required to place the ingot around all sides of the pot.
A Foundry environment, extreme temperatures and molten metal were factors in choosing the correct handling solution. Customer had a limited budget to fulfill needs of a new work cell. Previous Positech Manipulator was taken out of service due to new work cell functions.
Long parts are laying horizontal on the welding table at a 30° down angle. The catalytic converter is towards the operator. Parts are placed into the rack vertically and the catalytic converter is away from the operator at at a 15° forward angle. Intake tube on the bottom of the part is lifted over and onto a 3″ stud. exhaust tube snaps into clips at the top of the rack.
The Differentials are not large, but are heavy and hot. While there is only one size of Differential, the operator must reach into the mold to extract the part and manually rotate it.
